To all whom it may concern:

Be it known that l,A JOHN LALLY, a citizen of the United States,residing at Waltham, in the countyof Middlesex and State ofMassachusetts, have invented a certain new and useiul Column, oi whichthe following is a specification, reference being had therein to theaccompanying drawing.

This invention relates to columns, and the object of the invention is toprovide a simple and effective union or combined cap and base 'wherebythe members or sections oi a sectional column may be securely coupledtogether.

A further object of the invention is to provide coupling means of thecharacter above referred to which will enable the column sections to befilledwitha plastic composition and thereby rendered fire proof andadapt'- ed to sustain enormous pressure.

A further object of the invention is to provide coupling means of thecharacter referred to by means of which the sections of the column whenfilled withl plastic composition will be securely and firmly anchored orvof which will more ully appear as the description proceeds, theinvention consists in the novel construction, combination andarrangement of parts as hereinafter fully described, illustrated andclaimed.

In the accompanying drawings: Figure 1 is a vertical diametrical sectionthrough a column embodying the present invention. Fig. 2 is asectional'plan view of the same. Fig. 3 is a reduced sectionv similar toFig. 1 showing some slight changes in construction, but involving thesame principle. Fig. 4 is a similar section showing the combined columncap and base'formd integrally, Fig. 5 is a similar section showing amodification in the construction of the lower end of the upper columnsection"` F ig. 6 is a sectional plan viewl oi the arrangement shown inFig. 3. i

The preferred embodiment of my invention is clearly illustrated in Figs.1 and 2 in which 1 designates what we will term the upper column sectionand 2 the lower column section, while 3 designates the main body portionof the combined cap and base. It may be stated at this point that acolumn maybe made up of any desired number of sections 1 and 2 with thecomplemental unions consisting ofthe combined column cap and base to beherein particularly described. Each of said column sections may be ofany suitable length and is in the form of a tubular metallic casing themajor portion oi `which is designed to be filled with a plastic materialwhich subsequently hardens within the column'section and renders the.same solid throughout and fire proof.'

The main body portion of the union is of cyl indrical form as indicatedat 3 in Fig. 1 and may beoi any desired height, but preferablyof thesame diameter externally as the column section abutting against thesame.

At its lower end, the body of the cap ior the lowerl n column section isprovided with a flange 4 annular in shape and ofi-set inwardlysufiiciently to, allow an annular key space 5 betweenthe inner wall ofthe column sectionand the outer surface of said flange as clearly yshown in Fig.` 1, and the outer surface of said ange 4 is corrugated orribbed and grooved as shown so that when f l the plastic compositionhardens between the column section and said fiange, it forms a key orbond which anchors the column cap to the column section 2. By offsettingthe flange 4 inwardly as shown, an additional'annular shoulder 6isprovided within the cap 3 which also obtains a rm hold on the plasticlli'ng. In this way the cap and underlying column section are firmlybondv ed and tied together.

In its upper portion and outer face, the head portion 7 of the cap 3 isprovided with a recess 8 adapted to re.-

ceive a nut 9 screwed upon the upperextremities of an anchor 10 whichextends downward within the cap 3 and into the underlying column section2, said anchor being in the form of a bolt or rod as shown in Fig. 1provided at one end with an enlarged head or flange l0 which becomesembedded in the central portion o the plastic filling and serves as anadditional means for fastening the cap on the underlyingcolumn section.If desired, a clamping or lock xnut 11 may be placed upon the anchorl-beneath the top 7 thereof'so as to vhold the anchor fixed andcentrally within the cap. It

member of the union which comprises a body portion or base 13 preferablysecured to the top of the cap by lag screws 14 which pass throughopenings in the projecting corners 15 of the base 13 and into threadedsockets in the cap as indicated in Fig, 1. Extending upward from thebase orbody'13 is a flange 1G which is of less diameter externally thanthe internal diameter of the ad- 4 jacent column 1, .the flange 16correspondingin all particulars with thefiange 4 of the cap 3hereinabove particularly described, the s'aid flange' 16 having itsouter posed column section enters between said column sec-l tion and thecorresponding iace oi the flange iii, forming a bond or key whichsecures such column section to the column cap and base.

posed combined column cap and base. Extending laterally and horizontallyoutward from the caps 3 at one, two er more points are beam rests li)upon which the inner adjacent ends of iloor beams or rafters 2O arestipported as shown in Figs. l and 2. The rcsts 19 are reinorced'bybracing webs 2l. which, in Figs. l. and 2, are shown as extending fromthe rests i9 upward, heilig connected to the cap 3 or formed integrallytherewith.' The bracing webs 2l are also shown as preferably providedwith extensions or lugs 22 through cach pair oi` which is inserted abolt 23 which passes through the web of the adjacent eye beam 2() asbest shown in Fig. 2, spacing sleeves or washers 24 being interposedhetween the bracing Webs2l and the web the beam 2O and around the bolt23, thus securely holding the beam i to the column and preventing thepossibility of any lateral niovement or vibration of said beamrelatively to the column.

The construction illustrated in Figs. .3 and G cmbodies the lsameprinciple as that hereinabove described differing therefrom only incertain details oi shown as extending downwardly instead o1' upwardly.Another' difference resides in placing the cap plate 25 upon the upperedge of the/[lange i6 i'or the purpose 'ot' preventing the plasticfilling from passing around and holding the nut 9 of the anchor 10. Inorder to secure the cap plate 25 in place, another anchor 2G similar inevery .respect to the anchor l0 hereinttovc described, may be associatedwith the cap plato 25 as clearly shown in Fig. 3, anchor 2G beingdisposed reversely to the anchor li), with the enlarged head therwfupward.

Instead of forming the flange i6 separate i'rom the cap 3 and securingsaid parts together, the said parts may be integrally formed as shown inFig. 4. An additional fastening means is illustrated in Fig. 5 in whichthe inner face of the cap is shown as provided at intervals withinwardly exondiiig key projections 28 which bocome embeddodlln theplastic filling. It is also contemplated to secure a reinforcing cup inthe lower end of the superimposed column section 2 as shown in said Fig.5, said cup embodying the imperi'orate base portion 29 and the annularside portion 30 which i its snugly within the lower end of the columnsection--lZ--and over In this way the adjacent column Y sections aresecurely fastened together' by the interconstruction. For instance, thebracing webs 2l are 'i l l l i l l l ing the same true, preventing thesame from bending,`

and at the same time serving as a guard to prevent the plastic fillingfrom covering and burying the nut 9 of the anchor l0. Preferably the cupiits snugly around the ange 16 and thereby acts to enter the uppercolumn section with reference to the combined column cap and base.
